Chicken recipes are a favorite! There are so many dinners to come like TGI Friday’s Sizzlin Chicken and Cheese or Olive Garden’s Chicken Piccata! This Mushroom and Chicken Casserole is mighty delicious!


Chicken Casserole Recipe

A chicken casserole is good, but if you can add mushrooms and make your own homemade gravy instead of using canned soups then it’s a total win! Chicken Gloria recipes typically call for canned soups like canned creamy mushroom soup, which in my opinion is a turndown if I’m cooking dinner for the family! I like better-for-you options when it comes to certain things and canned soups aren’t my thing.

I put this Chicken Casserole together after some brief research and knowing what I did and did not want to use. Sour cream struck my attention and cheese and chicken always sound like a good idea so I put them together to create something even better than a usual chicken casserole! This casserole comes out ultra-creamy and the chicken is super tender while being smothered all over with a homemade canned soup if I may say! It’s a chicken recipe that can easily be the centerpiece of a guest dinner or the eye-catching potluck find. Serve it with a bed of creamy mashed potatoes and you will be favored!

Secret Ingredient

Cheese adds creaminess! Melt some into the gravy and the gravy will stay creamy from the cheese! This stuff is so good you can ladle it over your favorite pasta to make a Chicken Alfredo Dish! Talk about Fettucine Alfredo!

How to make a Chicken Casserole:


What is Chicken Gloria?

Chicken Gloria is a baked chicken casserole made with mushroom gravy and sometimes cheese. It usually calls for canned mushroom soup but this recipe calls for a homemade gravy instead!

What other Vegetables can I cook this Chicken Casserole with?

A Chicken Gloria Casserole is typically cooked with chicken and mushrooms. However, here is a list of vegetables that can be added in:

  • broccoli
  • bacon
  • cauliflower
  • green beans
  • sliced carrots
  • asparagus
  • Brussel sprouts
  • bell peppers

Ingredients for Creamy Chicken Casserole?

This chicken Casserole calls for basic ingredients and the cheese can easily be swapped out for another kind.

  • chicken- use chicken breasts or tenders.
  • flour- make it gluten-free by using cornstarch instead.
  • salt and pepper- flavors the casserole!
  • oil for frying- use vegetable oil, canola oil, or soybean oil.
  • fresh white button mushrooms- the most common mushroom and easy to access!
  • garlic- crushed from cloves.
  • unsalted butter- if using salted butter simply omit some of the salt in the recipe.
  • chicken broth- use 2 tsp of chicken bullion powder to 2 cups of water for the chicken broth.
  • heavy whipping cream- can use milk or half and half.
  • sour cream- I used the Daisy brand.
  • Muenster Cheese- can use Monterey cheese, Colby, or Mozzarella.
  • paprika- gives the chicken dish a hue.
  • vinegar- adds a bit of tartness to all that creaminess!

Can I make it Gluten-Free?

Corn-starch makes a great flour substitute especially when it comes to making gravy or slurries! Be careful not to use too much of it as it can leave a starchy after taste.

What to serve with a Chicken Casserole?

Since this chicken recipe resembles a tasty gravy side dishes like mashed potatoes or rice go best! Turn it into an Alfredo dish by ladling it over Pasta! Fresh salads make a great side too like this cucumber cabbage salad or creamy cucumber tomato salad.

Can Chicken Gravy be frozen?

If you didn’t know gravy actually freezes very well! I freeze my sausage gravy for a future biscuit breakfast and like to pop leftover gravy into the freezer for reheating later! This chicken casserole can be frozen too!

To freeze Chicken Gloria: use a disposable baking dish to layer all ingredients per recipe. Cool completely. Cover with foil and freeze up to 3 months.

To reheat: Thaw completely and bake as instructed for 45 minutes or until hot and bubbly.

Can I make-Ahead?

This kind of casserole is great for making ahead since everything is layered before baking anyways! Here is how!

How to Make Creamy Chicken Casserole ahead of time: Layer the chicken, mushrooms, and gravy per recipe. Cool completely. Cover and refrigerate for up to 3 days. Bake at 350°F for 45 minutes or until bubbly and hot.

Slow Cooker Instructions:

  1. Season and dredge the chicken into the flour. Place into a 5-quart slow cooker.
  2. In a medium saucepan saute the mushrooms and onion for 10 minutes. Place over chicken.
  3. In the same saucepan melt the butter and stir in flour. Add the remaining gravy ingredients and pour over the chicken and mushrooms. Cook over low for 4-5 hours or high for 3 hours.


  1. Use a deep frying pan to make this chicken casserole as gravy later cooks in it!
  2. Baking soda makes a quick meat-tenderizer!
  3. Season meat directly rather than mixing it into the flour that way it’s not left behind in the flour.
  4. Use the excess dredging flour for the roux in the gravy.

    I wanna make this but confused about the
    6 oz Muenster cheese, do you just put the slices in the gravy? It doesn’t come in the shredded form.

      • Alyona Demyanchuk

      Hi Tanya, you would grate it.

        • Tanya

        Made it for tonight’s dinner, it was delicious!

    • Penny Cathey

    I tweeted this recipe to fit my kitchen and hearty hubby’s appetite. I used 4 huge Chicken Leg Quarters. I fried the mushrooms, added red, yellow, orange peppers, green Onions, SPINACH, garlic pour over the pan fried Leg quarters, Then followed her next step with the butter, flour, chicken stock, heavy cream & sour cream. But when I went to pour that yummy white gravy over those chicken quarters, I knew all that white gravy was not gonna fit in that 9X13 pan. I placed the chicken quarters in an old-fashion black roaster pan, pour all that white gravy on top, sprinkled with the 1/4 tsp of paprika and then placed the roaster in the oven for that last 40 minutes. I wish I could attach the photo. 😉

    This was absolutely delicious! We will be making it again for sure, thanks!

      • Alyona Demyanchuk

      I’m so glad it’s a repeat, Lori!

    • Irene D

    Delicious recipe Alyona! The gravy itself is a keeper. Will definitely be referring back to this. Love that you can make it ahead of time, then just pop it in the oven:)

      • Alyona Demyanchuk

      Thanks, Irene! I’m glad you enjoyed it!

    • Katherine

    Do you add onions to your casserole? The instructions mention onions but I didn’t see them in the ingredient list. Thanks!!

      • Alyona Demyanchuk

      Hi Katherine, yes, it does have onions! Sorry about that I fixed it.
